An absolutely marvelous and simple lamb recipe that even people who don't like lamb love, courtesy of my Aunt Stephanie. It's my go-to recipe for Passover Seder, and always gets rave reviews. Best done on a grill, it still works just as well under the broiler, and looks spectacular thanks to the butterflying, regardless of which method you choose. It's also just as yummy cold as freshly cooked, if not even better. I seem to remember this actually serving a lot more than 6-8 people, but this is what another very similar recipe said is the yield. I've never really paid attention to that or the weight of the lamb I've bought, but had to come up with a number for here.
